Abstract
The utility model discloses a kind of automobile start circuits, including sensor, control element and executive component；The sensor is mounted on Automobile flywheel, the detection for carrying out distance between motor gear and flywheel, and the data detected are sent to control element；The control element receives transducing signal, and signal is passed to executive component, and the executive component generation action disconnects electromagnetic switch power cord, to cut off engaging for motor gear and flywheel ring gear.The utility model can prevent automobile start engine flywheel and the abnormal engagement of starter, protect engine flywheel and starter, ensure the safety of automobile.
Description
Technical field
The utility model is related to automotive fields, and in particular to a kind of automobile start circuit.
Background technology
Currently, existing starting control circuit and operation principle are as follows：
Connection column → electric power storage of accumulator → ignition switch start gear → motor electromagnetic switch → connection accumulator to motor
Tank discharge generates prodigious electric current, drives motor rotor rotation → rotor rotation, while motor teeth directional free wheel direction moves, and makes
Motor gear successfully engages with static flywheel ring gear → and flywheel rotation at a slow speed → engine works → unclamps ignition switch, returns to
One grade of ignition switch, start gear disconnection → motor electromagnetic switch is without electricity → motor gear self-return → motor gear and flywheel ring gear point
From.
It can be seen that it does not all account for engine in the operating condition, the case where making motor is artificially missed, so that automobile
It starts engine flywheel and the abnormal engagement of starter substantially reduces the service life of part so that gear is fragile.
So research " innovative design of automobile start circuit and put into practice " cut-out motor gear and dynamic flywheel gear ring engage,
To the effect of protection gear, extends part service life and have great importance.
Utility model content
To solve the above problems, the utility model provides a kind of automobile start circuit, it can prevent automobile start from starting
Machine flywheel and the abnormal engagement of starter protect engine flywheel and starter, ensure the safety of automobile.
To achieve the above object, the technical solution that the utility model is taken is：
A kind of automobile start circuit, including sensor, control element and executive component；The sensor flies mounted on automobile
On wheel, the detection for carrying out distance between motor gear and flywheel, and the data detected are sent to control element；The control
Element processed receives transducing signal, and signal is passed to executive component, the executive component generation action, by electromagnetic switch power supply
Line disconnects, to cut off engaging for motor gear and flywheel ring gear.
Preferably, the control element is microcontroller, using AT89S51 the stc89c52 microcontrollers of 51 series
Preferably, the executive component uses relay switch apparatus, mounted on the point switch and accumulator of starter
Between starter relay before.
Preferably, the sensor is the lambda sensor and crankshaft position sensor of engine interior.
The utility model has the advantages that：
The utility model can prevent automobile start engine flywheel and the abnormal engagement of starter, protect engine flywheel
And starter, ensure the safety of automobile.
Description of the drawings
Fig. 1 is a kind of schematic diagram of automobile start circuit of the utility model embodiment.
Fig. 2 is a kind of circuit diagram of automobile start circuit of the utility model embodiment
Specific implementation mode
In order to make the purpose of this utility model and advantage be more clearly understood, with reference to embodiments to the utility model into
Row is further described.It should be appreciated that specific embodiment described herein is only used to explain the utility model, and do not have to
In restriction the utility model.
As shown in Figure 1, the utility model embodiment provides a kind of automobile start circuit, including sensor, control element
And executive component；The sensor is mounted on Automobile flywheel, the detection for carrying out distance between motor gear and flywheel, and will
The data detected are sent to control element；The control element receives transducing signal, and signal is passed to executive component, institute
Executive component generation action is stated, electromagnetic switch power cord is disconnected, to cut off engaging for motor gear and flywheel ring gear.The control
Element processed is microcontroller, and using AT89S51 the stc89c52 microcontrollers of 51 series, the executive component uses relay
Switching device, before the starter relay between point switch and the accumulator of starter, the sensor is engine
Internal lambda sensor and crankshaft position sensor.
The circuit diagram of this specific implementation as shown in Fig. 2, microcontroller by detecting lambda sensor and Hall sensor
Signal, judge whether engine starts, relay made to execute action.When judging engine start, just make relay switch
In normally opened, starter fail to start；When judging engine unstart, relay switch is just made to be in normally off, starter
It can start.
This specific implementation judges whether automobile starts by the signal that sensor detects, using control units such as microcontrollers,
Relay is set to disconnect the circuit being connect with starter, so that user will not start twisting key again to start position
Engine, to avoid artificial the occurrence of accidentally making motor well.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, can also make several improvements and retouch, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
